I really Like the Shimano Steps system. Owned an e8000 an now Ep8 but next ebike will be from a other brand. Mainly because they handle problems the way they do it with the battery issue right now. Not very comsumer oriented.
Of course its Software related, shimano uses normal cells like every other brand.
Were it cell related not every battery would degrade exact the same amount in the same cycles.
So its out of question that its the Software that absolut shit. I wonder when the first batch with better software...
You got that wrong. If you want to avoid that Problem and still ride a Bike with Shimano Motor get a bike designed with a battery from a third party like the New Santa Cruz Heckler or Focus Jam they come with a Darfon battery.
But if they are more reliable is another topic

Shimano changed something with the last update. At least thats what i think, because the battery Life on my 2 BT-E8035 increased by 6%.
1. Battery - before Update 85% to 91%
2. Battery - before Update 87% to 93%
And the strange drops after every 10 cycle are gone.
